ABSTRACT:
A bottled water/tap water cooler and compact oxygen generator system combined within a single housing structure. The oxygen generator includes an air compressor for generating compressed air and uses two molecular sieve beds that operate one after the other. As a first molecular sieve bed absorbs nitrogen, up to approximately 95% pure oxygen is allowed to pass therethrough to a flow meter and into a diffuser which passes the oxygen into a purified drinking water reservoir supplied by the bottled water or filtered tap water. After the first molecular sieve bed is full, the second molecular sieve bed activates and starts absorbing nitrogen while allowing oxygen to pass therethrough, simultaneously, nitrogen is vented from the first molecular sieve into the atmosphere. The first and second molecular sieve beds alternate with one another allowing the system to run continuously by using timer controlled dual 3-way valves.
